Meteorological authorities in St. Vincent and the Grenadines have issued a 72-hour weather outlook warning residents, motorists, and mariners to prepare for unsettled weather, isolated thunderstorms, and hazardous marine conditions beginning Tuesday evening.
Fair to partly cloudy skies on Tuesday morning are expected to give way to increasing cloudiness by Tuesday evening, bringing a few showers and isolated thunderstorms. The core of the atmospheric disruption is driven by an approaching low-level trough scheduled to cross the region by late Tuesday into Wednesday. On Wednesday, November 11, conditions will become occasionally cloudy and breezy, accompanied by scattered showers and thunderstorms. Official weather advisories instruct residents and motorists living or traveling near rivers, streams, and areas prone to flash-flooding or landslides to remain alert throughout the mid-week period.
Unsettled weather will persist into Thursday, November 12, with partly cloudy to cloudy skies, periodic breezes, scattered showers, and isolated thunderstorms continuing across the islands.
Additionally, atmospheric tracking indicates that a Saharan dust patch will create slight to moderate haze over the area by Thursday. Wind patterns will transition from gentle to moderate southeasterly breezes of 12 to 25 kilometers per hour toward a northeasterly direction, with localized wind speeds occasionally gusting up to 30 to 35 kilometers per hour.
Coastal and marine environments face heightened risk throughout the 72-hour period due to incoming northerly swells and occasional long-period breaking wave action along the coastlines of St. Vincent and the Grenadines. Open-water sea conditions, currently ranging between 0.5 and 1.2 meters, are projected to build gradually by mid-week, reaching heights up to 1.0 meter west of the islands and up to 1.8 meters east of the islands. Weather officials have advised small-craft operators and sea-bathers to exercise extreme caution when venturing near the water.
The St. Vincent and the Grenadines Meteorological Services emphasized that while the 72-hour outlook provides essential advance guidance, members of the public should monitor daily weather updates for real-time localized changes as the low-level trough progresses across the eastern Caribbean.
